Leviticus 23:23-28

King James Version

²³ And the Lord spake unto Moses, saying,

²⁴ Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation.

²⁵ Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the Lord.

²⁶ And the Lord spake unto Moses, saying,

²⁷ Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the Lord.

²⁸ And ye shall do no work in that same day: for it is a day of atonement, to make an atonement for you before the Lord your God.
